"Windows Server 2025 domain controllers (such as servers hosting the Active Directory domain controller role) might not manage network traffic correctly following a restart," Microsoft said in a Friday Windows release health dashboard update. Microsoft warned IT admins that some Windows Server 2025 domain controllers (DCs) might become inaccessible after a restart, causing apps and services to fail or remain unreachable. Earlier this month, Microsoft warned that some Windows users might be unable to log into their accounts using Windows Hello after installing the KB5055523 April 2025 security update. However, it's also important to note that admins must restart the network adapter after every reboot because this known issue triggers whenever the domain controller is restarted. Microsoft also pointed out that this can be addressed by manually restarting the network adapter on impacted servers using various methods, including the following PowerShell command: Restart-NetAdapter *. Because of this known issue, services and applications running on affected DC servers or remote devices may fail or become unreachable for other endpoints and servers on the network. Microsoft also fixed another KB5055523 issue, which caused authentication issues when Credential Guard was enabled on systems using the Kerberos PKINIT pre-auth security protocol.
